f plioationfiled December 26,189? Seria1No.494 691- (No modelJ' To all whom it may concern.-

Be it known that I, JACOB S. DETRIOK, of the city of' Baltimore and State of Maryland, have invented certain- Improvements in Bottle-Sealing. Devices, of which the following is a specification.

This invention relates to certain improvements in that class of bottle sealing devices in which a compressible seal is held in contact with a seat formed of a part of the bottle, by means of a holder; and it consists in combining with a bottle head, having in its mouth a seat and a lip or projection above the seat, a compressible seal and a holder which is contracted in size as it is forced into the mouth of the bottle and onto the seal to compress it, and which expands or is expanded so as to bring a portion of its upper edge circumference under the lip or projecr tion and thereby holdthe said seal firmly in place, the remaining portions of the edge being within the said lip so as to provide spaces into which an extracting device may be introduced as will hereinafter fully appear.

In the further description of the said invention which follows, reference is made to the accompanying drawings forming a part hereof, and in which, the invention is shown in various forms hereinafter described.

Referring to Figures 1 and 2, which are, respectively, a vertical section, and a plan of the upper part of a bottle embodying the invention, A is the bottle, and a. the head of the same.

The seal seat is denoted by b, and the projecting lip which is situated over the seat,

by c. 7

B is the compressible seal formed of any suitable material, preferably cork, which rests on the flat annular surface or seat 17.

Gis the spring seal holder which consists of a metallic cup with its bottom recessed to receive the seal B, and its upper edge corrugated, so that portions only of its circumference project under the lip c. In other words the outer diameter of the corrugated edge of the cup shaped holder, is somewhat greater than that of the portion of the bottle mouth above the lip or projection 0, while the inner diameter of the corrugations is considerably less, consequently, there appears, when the sealed bottle is viewed from its end, a series of exposed depressions into any one of which an extracting tool may be forced to effect the removal of the sealing device, as will hereinafter more fully appear.

The sealing of the bottle consists merely in forcing to its seat the compressible seal by means of the holder; or forcing in the holder and seal until the edge of the former passes to below the lip c and expands so as to bring theouter corrugations ofits edge under the same.

To unseal the bottle, an instrument consisting preferably of a rod, is forced into one of the spaces made by corru gating the upper edge of the holder, and then using it as a lever to crush in the side of the holder, and thereby practically-reduce its diameter. By continuing this movement of the tool, the sealing device is ejected from the month. In this operation the seal is either removed with the holder or forced out by the contents of the bottle. 7

I have shoavn the cup as provided withten corrugations, but any number may be em- ;ployed, and a reduced number is perhaps preferable.

. Referring now to Figs. 3 and 4, the former being a vertical section, and the latter a cross section of Fig. 3, taken on the dotted line a:x, it will be seen that the seat b instead of being hat is conical, but in other respects, the construction shown in the preceding figures, is preserved.

Referring now to Fig. 5, which is a vertical section of a bottle, and its sealing device, it will appear that the seat is concave, and the seal concavo-convex, which shape is efiected in the act of sealing by the sealing cup which has a rounded bottom.

In Fig. 6 theseat is convex and the bottom gated upper edge, in contact with the under side of the said projection or lip, substantially as specified,

2. In combination with a bottle having in This construction its month an annular seat and above the seat a projection or lip, a seal, and a seal holder with a corrugated edge which occupies the space between the seated seal and the lip, substantially as specified.

3. In combination with a bottle havingrin "its mouth a seat, and alipor'projection above the seat, a seal anda cup-shaped holder, having its upper edge corrugated, to give space for the insertion of an extracting tool, substantially as and for the purpose specified. JACOB S. DETRIOK.
